Question

13. We are curious to see if college students get less sleep than the average person. It is known from previous studies that the average person gets 8 hours of sleep on average with a standard deviation of 1 hour. We surveyed 100 students from LTCC and found that on average they got 7.5 hours of sleep with a standard deviation of 1.5 hours.

c) Analyzing the data, we get a 95% confidence interval of (7.206, 7.794). What should our conclusion be?
